Specification of Letters Patent.

Patented June 5, 19b6.

Application filed December 21, 1899. Serial No. 741,146.

Be it known that I, FRANK J. REINHOLD, a citizen of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Box-Making Machines; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention relates to improvements in machines for manufacturing paper boxes and is shown in the accompanying drawings, in which Figure 1 is a plan view. Fig. 2 is a side elevation, partly in section. Fig. 3 is a view showing details of the re-pressing device. Fig. 4 is a plan view of the same, partly in section. Fig. 5 is a sectional view showing the manner of inserting, re-pressing, and carrying the boxes in the wheel one over another in series.

In the drawings, A represents the table or bed of the machine, which may be supported upon any suitable standards. B is the main shaft of the machine, mounted in bearings B and B the shaft being parallel with the table. The bearing B is supported from the table on the vertical support 5, and the bearing B is supported on the vertical support 6. The main shaft B is driven by any suitable means and is provided with the hand-wheel B at the front of the machine to provide means for turning the shaft by hand in adjusting the machine. 5 is a rod extending through underneath the bed and is provided at the front of the machine with a small handwheel 6 This shaft operates the clutch mechanism at the rear of the machine, whereby the operator from in front can start or stop thesame at will.

The machine is provided with the usual means for feeding paper or cardboard, for scoring it, for gluing it, and for cutting it off. The glue mechanism is underneath the machine and is not shown, except the camOand the connecting-rod c. The paper travels on the line D and is first operated upon in the machine by the slitting device E, operating from cam C. This device cuts two parallel slits in the paper at the point where it is to be cut off and in such a manner that the slits will extend an equal distance into each blank, leaving between the slits what is known as the "end flaps and outside of the slits the side flaps. The slitting device moves up and down in the machine in guides formed in the standard E.

The feeding device consists of the feedingrolls F and F, mounted in the vertical standard F These rolls are geared together and are driven from the gear F mounted in the standard E.

F is a transverse rock-shaft mounted in the standards F and is rocked by means of the arm F and the cam C F is a horizontal arm attached to the rockshaft F, the free end of which is caused to move up and down as the shaft is operated by the cam O f is a connecting-rod operated by the arm F. The reciprocated movement of this connecting-rod is communicated to the driving gear-wheel F through a ratchet mechanism in the usual manner, whereby the feedingrolls are given the necessary intermittent movement for feeding the paper.

G is a supporting-frame that is bolted to the bed and that rises to a sufficient height to form the support for the bearing B and to serve as the uide for the former-plunger H, as well as the plunger I, bearing the knife i for cutting off blanks.

The plunger I is operated by the cam C and the former-plunger H is operated by the cam C The means for cutting off the blank and for forming the box from the blank are quite similar to those employed heretofore in the art.

The cardboard is fed under the formerplunger by the operation of the feeding-rolls, and through the action of the cams the former-plunger and the knife move downward until the knife severs the blank from the sheet, after which the continued move ment of the former-plunger forces the blank downward into a female die, folding up the side of the box, leaving the end fiap extending in a horizontal direction and the side flaps standing in a vertical direction. As is common in this class of machines, the formerplunger rests a moment, while the foldingfingers c move in to fold in the side flaps. These fingers are operated from the cam c through the rock-arm c, the rock-shaft c and the arm 0". After the side flaps are folded in the former-plunger continues its movement down into the female die, folding the end fiaps up against the side flaps and plunger and then carrying the whole box downward into a pocket J, formed in a horizontal carrying-wheel K. This wheel is provided with a series of these pockets, preferably about ten in number, and the wheel itself is mounted on the hollow hub K. The wheel proper is formed of one casting, the outer ends of the pockets being closed by the plates 19. As the former-plunger forces one box into the pocket it forces the box already in the pocket downward to a lower position, and after the pockets are filled with boxes the entry of a new box in the top of the pocket discharges a completed box from the bottom.

L is a bar arranged to reciprocate along the side of the machine and is operated by the arm L, fixed to the shaft F On the bar L is pivoted a dog M, which engages with the periphery of the wheel K as the bar is operated to move the wheel forward a suificient distance to bring another pocket under the plunger. To the outer end of the bar L is pivoted a second dog M, which engages with the wheel to lock it when it is at the point of rest and during the time the former-plunger is forcing a box into one of the pockets of the wheel. N is a friction-plate arranged to be drawn down on the hub to increase the resistance to its movement.

0 is a re-pressing device arranged to enter the pocket in the wheel that is directly opposite the one under the former-plunger. The purpose of this re-pressing device is to force the glued surfaces of the box a second time into close contact and at the time when the glue is partly set or beginning to set. The means I employ for accomplishing this result consists in an expanding plunger consisting of the opposite sections 0 0, the two sections being held in operative relations on and by the pins p p and being normally drawn toward each other by the springs 79" p". This expanding plunger is fixed to the plungerrod P, and the rod are arranged to move up and down in a way formed in the standard P. The plunger-rod and plunger are -moved up and down simultaneously with the formerplunger by the lever 10 the end of the lever being engaged with the former-plunger by a universal oint p Extending out from the plunger-rod P are supports p p", in which is mounted a vertical cam-rod 10 provided with the cam p at its lower end located between the sections of the expanding plunger.

The cam-rod p is provided with an arm 79, which travels along the surface of a cam p fixed to the standard P, the construction being'such that the cam-rod p is given a part of a turn as it travels down, the rotation of the rod causing the cam p to force the opposite sections of the plunger 0 apart and against the glued sections of the box.

One of the purposes of my invention is to reduce the size of the carrying-wheel without reducing the number of boxes it is capable of carrying. This I accomplish by using a wheel having only a small number of pockets and by making the pockets in the wheel of sufficient depth to carry two or more boxes. In using this construction I first operate the machine in the manner common to this class of machines until the wheel has made one complete circuit, when a second series of boxes is placed in the pockets over the first .series, the box in each pocket being forced down as a new box enters. If the pockets are deep enough to carry, say, four boxes, then a wheel having but ten pockets will carry forty boxes before any are delivered. This gives the glue time to dry. This con struction and use is illustrated in Fig. 5, in which two of the pockets in the wheel are shown, both filled with boxes, three boxes in each pocket.

76 7c represent the boxes in the pockets, and 71? the box being delivered from the pocket under the former-plunger by the insertion of the fourth box in the pocket by the formerplunger. Q

To more perfectly glue the boxes, I employ the re-pressing device, "which operates upon the boxes in the pocket after the glue has partly dried or set. Those familiar with the use of glue will understand that the second operation of pressing the glued surfaces together will have the effect to cause the surfaces to adhere where the first operation may have failed. The result of this second or repressing is to form a stronger box and one of better form.

To provide for steadiness in the operation of the carrying-wheel, a friction device is used to prevent too much or too quick movement of the wheel. For this purpose I mount the wheel or carrying-rim upon a large hub, and in addition to the friction provided by the enlarged friction-surfaces I add a spring friction device.

I would also have it understood that in the use of the expanding plunger I do not limit myself to re-pressing devices alone, as the former-plunger may be made to expand to force the glued surfaces more closely into contact than can be conveniently done by forcing them through the folding devices. I use the term expanding plunger, but the pressing device may not be strictly a plunger in every case, and I do not desire to limit my self by the use of the term most adapted to describe the instrument used in the construction herein shown and described.
